car a travels 120 miles in the same time that car b travels 150 miles. if car b averages 10 mph faster than car a, what is the speed of each car?

  Car A: 40 mph

  Car B: 50 mph

Step-by-step explanation:

For the same travel time, the ratio of speeds is the same as the ratio of distances:

  (speed B)/(speed A) = 150/120 = 5/4

The difference in the (reduced) ratio units is 1, so 1 ratio unit corresponds to 10 mph. Multiplying the reduced ratio by 10 mph, we get ...

Speed B is 50 mph; speed A is 40 mph.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
